Description

Technical Field

[0001] The utility model belongs to the technical field of fastener processing and relates to a bolt gasket error-proof interception device for a conveyor track. Background Art

[0002] During the assembly process of mechanical equipment, in order to prevent the fastener bolts from loosening, they are usually used in conjunction with gaskets. In order to avoid the gaskets being lost or installed incorrectly later, during the processing of the fasteners, gaskets are usually pre-installed directly on the bolts.

[0003] In the past, gaskets were installed on bolts one by one manually, which had low assembly efficiency. Due to the large number of installations and the fact that gaskets have positive and negative sides (the smooth edge with rounded corners is the positive side, and the smooth side with rounded corners is usually facing the nut, so that when tightening the bolt, the friction between the bolt and the gasket can be reduced, and the friction between the gasket and the contact surface of the equipment can be increased to prevent loosening), manual assembly is prone to installing gaskets upside down. Currently, bolt gasket automatic assembly machines have appeared on the market, which can automatically install gaskets directly on bolts, greatly improving assembly efficiency, but they still cannot guarantee the installation direction of gaskets, and they still need to be checked manually, which is time-consuming and labor-intensive, and is prone to missed inspections. Summary of the invention

[0004] The purpose of the utility model is to address the above-mentioned problems in the existing technology and to propose a bolt gasket anti-error interception device for a conveyor rail, which can intercept bolt gaskets that are assembled in the wrong direction, eliminating the trouble of manual inspection and greatly improving the inspection efficiency.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A bolt gasket error prevention interception device for a conveying track, wherein a conveying channel is provided in the middle of the conveying track, gaskets are mounted on the bolts, and the bolts with gaskets are transported through the conveying channel, and the error prevention interception device comprises two limiting mechanisms, which are symmetrically arranged on both sides of the conveying track, and the limiting mechanisms comprise:

[0007] A mounting block, wherein the mounting block is detachably mounted on the outer side of the conveying track, and two supporting plates are arranged in parallel on the upper side of the mounting block, and a fixed shaft is fixed between the two supporting plates;

[0008] The intercepting plate is movably arranged between the two supporting plates, and an arc-shaped notch that matches the front edge of the gasket is opened on the lower side surface of the intercepting plate close to the conveying channel.

[0009] Preferably, two first slide slot holes are vertically opened on the mounting block, a first stud is inserted into the first slide slot hole, the inner end of the first stud passes through the first slide slot hole and the end is fixed on the outer wall of the conveying track, the outer end of the first stud extends to the outside of the mounting block and the end is threadedly connected with a first butterfly nut.

[0010] Preferably, the two first slide slot holes are in the shape of long strips and are aligned vertically.

[0011] Preferably, a sliding clamp is vertically slidably provided on the outer side of the mounting block, and the sliding clamp is C-shaped. The two side plates of the sliding clamp are fitted with the two sides of the mounting block. Two first through holes are provided on the sliding clamp, and the two first through holes correspond to the two first studs one by one. The outer end of the first stud passes through the corresponding first through hole and the end is threadedly connected to the first butterfly nut.

[0012] Preferably, scale lines are provided on both left and right sides of the outer side of the mounting block.

[0013] Preferably, a second long slot hole is horizontally opened on the intercepting plate, and the fixed shaft passes through the second slot hole.

[0014] Preferably, an L-shaped fixing plate is provided on the mounting block, a third slide slot hole is horizontally opened on the side of the intercepting plate away from the arc-shaped notch, a butterfly bolt is inserted into the third slide slot hole, and the end of the butterfly bolt is threadedly connected to the fixing plate.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] 1. Install two mounting blocks symmetrically on both sides of the conveying track, and adjust the position of the mounting blocks. When the rounded front side of the gasket faces upward, the gasket on the bolt moving in the conveying channel can just pass through the arc-shaped notch of the interception plate. When the gasket is installed in the opposite direction, the bolt with the gasket will be blocked by the two interception plates. At this time, the bolt can be taken out manually, and the direction of the gasket can be adjusted and put into the conveying channel again, eliminating the trouble of manual inspection. The operation is simple, saving time and effort;

[0017] 2. When the thickness of the gasket is different, the first butterfly nut can be screwed outward to drive the mounting block to slide vertically up and down so that the height of the arc-shaped notch of the intercepting plate meets the requirements of gaskets of different thicknesses. In addition, when the gasket sizes are different, the butterfly bolt can be loosened so that the intercepting plate can move horizontally along the fixed axis so that the width of the arc-shaped notch of the intercepting plate meets the requirements of gaskets of different sizes, thereby improving the applicability of the device.

DETAILED DESCRIPTION

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments. Embodiment 1

[0026] like Figure 1-3 As shown, a bolt gasket anti-error interception device for a conveying track, a conveying channel 11 is provided in the middle of the conveying track 1, and the bolts 5 are assembled with gaskets 51 through an automatic assembly mechanism. The gaskets 51 have a smooth front and rounded sides, and the bolts 5 equipped with gaskets 51 are conveyed through the conveying channel 11 in sequence.

[0027] The error prevention interception device is installed on the conveying track 1 , and the error prevention interception device includes two limiting mechanisms, which are symmetrically arranged on both sides of the conveying track 1 , and the limiting mechanisms include a mounting block 2 and an interception plate 31 .

[0028] Two first slide slot holes 21 are vertically provided on the mounting block 2, a first stud 22 is inserted into the first slide slot hole 21, an inner end of the first stud 22 passes through the first slide slot hole 21 and an end portion is fixed on the outer side wall of the conveying track 1, an outer end of the first stud 22 extends to the outer side of the mounting block 2 and a first butterfly nut 23 is threadedly connected to the end portion, two support plates 3 are parallelly provided on the upper side surface of the mounting block 2, and a fixed shaft 33 is fixed between the two support plates 3.

[0029] The intercepting plate 31 is movably arranged between the two supporting plates 3. An arc-shaped notch 313 matching the front edge of the gasket 51 is provided on the lower side surface of the intercepting plate 31 close to the conveying channel 11. The arc-shaped notch 313 includes a horizontal segment, an arc segment and a vertical segment connected in sequence. The arc segment matches the rounded corner of the front side of the gasket 51, and the heights of the vertical segment and the arc segment match the thickness of the gasket 51.

[0030] The two mounting blocks 2 are symmetrically mounted on both sides of the conveying track 1, and the positions of the mounting blocks 2 are adjusted. When the rounded front side of the gasket 51 faces upward, the gasket 51 on the bolt 5 moving in the conveying channel 11 can just pass through the arc-shaped notch 313 of the intercepting plate 31. When the gasket 51 is installed in the reverse direction, the bolt 5 with the gasket 51 will be blocked by the two intercepting plates 31. At this time, the bolt can be taken out manually, and the direction of the gasket 51 can be adjusted and put back into the conveying channel 11, eliminating the trouble of manual inspection. The operation is simple, saving time and effort. Embodiment 2

[0031] like Figure 1-3 As shown, a sliding clamp plate 24 is vertically slidably provided on the outer side of the mounting block 2, and the sliding clamp plate 24 is C-shaped. The two side plates of the sliding clamp plate 24 are fitted with the two sides of the mounting block 2, and two first through holes 241 are provided on the sliding clamp plate 24. The two first through holes 241 correspond to the two first studs 22 one by one, and the outer ends of the first studs 22 pass through the corresponding first through holes 241 and the ends are threadedly connected to the first butterfly nuts 23.

[0032] When the thickness of the gasket 51 is different, the first butterfly nut 23 can be screwed outward to drive the mounting block 2 to slide vertically up and down, so that the height of the arc-shaped notch 313 of the intercepting plate 31 meets the requirements of gaskets 51 of different thicknesses.

[0033] In this embodiment, the two first slide slot holes 21 are in the shape of long strips and are aligned vertically, so that when the mounting block 2 is adjusted, the mounting block 2 can always maintain horizontal vertical movement.

[0034] In this embodiment, the left and right sides of the outer side surface of the mounting block 2 are provided with scale lines 6, and the height value of the mounting block 2 is read with the upper side edge of the sliding splint 24 as the indicator. At the same time, the value can be changed according to the thickness of the replacement gasket 51, and the mounting block 2 can be quickly adjusted to a suitable height position. The operation is simple and the adjustment efficiency is high. At the same time, it can ensure that the mounting blocks 2 on the left and right sides are at the same height, avoiding interception errors caused by inconsistent heights of the arc-shaped notches 313 on both sides, thereby affecting normal transportation. Embodiment 3

[0035] like Figure 4-6 As shown, a second long slot hole 311 is horizontally opened on the intercepting plate 31, and the fixed shaft 33 passes through the second slot hole 311. The intercepting plate 31 is movably set on the fixed shaft 33 through the second slot hole 311. When the intercepting plate 31 is not needed, the intercepting plate 31 can be rotated upward to away from the conveying track 1.

[0036] In this embodiment, an L-shaped fixing plate 4 is provided on the mounting block 2, and the upper side of the fixing plate 4 extends to the height position when the intercepting plate 31 is placed horizontally. A third slide slot hole 312 is horizontally opened on the side of the intercepting plate 31 away from the arc-shaped notch 313, and a butterfly bolt 34 is inserted into the third slide slot hole 312. The end of the butterfly bolt 34 is threadedly connected to the fixing plate 4.

[0037] When the size of the gasket 51 is different, the butterfly bolt 34 can be loosened so that the intercepting plate 31 can move horizontally along the fixed shaft 33, so that the width of the arc-shaped notch 313 of the intercepting plate 31 meets the requirements of gaskets of different sizes, thereby improving the application range of the device. In addition, when the intercepting plate 31 is not needed, the butterfly bolt 34 is turned outward to pull it out of the third slide slot hole 312, and the intercepting plate 31 can be rotated at will.

[0038] Preferably, a limit lever 32 is horizontally provided on one side of the two support plates 3 close to the conveying track 1. When the interception plate 31 is rotated to be horizontal, the lower side of the interception plate 31 contacts the limit lever 32, and the limit lever 32 can make the interception plate 31 quickly reach a horizontal position, which is easy to adjust and has a simple structure.
